Users with all kinds of setups have been reporting problems, affecting some GeForce 8800 cards, and particularly the GeForce 8800 GTS 320MB. According to users from NVIDIA, eVGA, NVNews, Rage3F and Guru of 3D forums, the problem causes random slowdowns, often halving frame rates until the user alt-tabs out of the game and back in again. The problem doesn't appear to be tied to any particular hardware configuration, Windows version, or display setting. NVIDIA Technical Marketing Director Nick Stam confirmed today that NVIDIA is aware of this issue, and new drivers will be released some time in July to fix the problem.
